5.18 Ct. Bi Color (Peacock) Tanzanite from Tanzania

This exceptional transparent 5.18 carat pear shape bi color peacock tanzanite measures 17.16 x 9.29 x 5.41 mm, it features a mixed brilliant cut that balances scintillation and color saturation, it is evaluated as eye clean at eye level with intense color intensity and an excellent polish, the stone has been heat treated which is the standard enhancement for tanzanite and it originates from Tanzania, offered by The Natural Gemstone Company. Compared with many market offerings this tanzanite stands out for its combination of size, clarity and color, most tanzanites of comparable carat weight present weaker saturation or visible inclusions, many stones are over cut to sacrifice color for size, while this piece retains deep peacock tones thanks to the skilled mixed brilliant cut which preserves the trichroic color shifts that make tanzanite unique. In value terms a natural Tanzanian stone of this quality and carat weight is rarer than similar looking stones treated to obscure flaws, the eye clean clarity means you receive a clean visual field without the need to compensate with larger size, the excellent polish ensures each facet returns light efficiently, producing a lively presence in jewelry that outperforms many commercially available specimens.

Under different lighting conditions this bi color peacock tanzanite transforms beautifully, in natural daylight the stone reveals cool blue and violet cores with greenish peacock flashes along the girdle and in the pavilion, the daylight spectrum emphasizes the intense color intensity and the overall transparency yields a deep, velvety appearance. Under warm incandescent or candlelight the stone shifts toward richer violet and occasionally warmer purple notes with subtle flashes of peacock green, this warmth enhances the gemfish glow and makes the stone read as more regal and saturated in evening wear. Under LED and halogen spot lighting the mixed brilliant facets come alive with brisk scintillation and crisp flashes, the excellent polish and facet geometry maximize light return, fluorescence from typical indoor lighting is minimal so color fidelity remains strong, when viewed from different angles the natural pleochroism produces distinct color shifts that reward movement, this dynamic performance in varied light makes this tanzanite a superior choice for a signature ring or pendant, The Natural Gemstone Company is proud to present this rare peacock tanzanite as an investment in beauty and lasting value.
